I got the list down to five corner cases, all involving multiple
commits related to a single issue.
https://gitlab.com/lilypond/lilypond/-/issues/154
https://gitlab.com/lilypond/lilypond/-/issues/1861
These two issues saw additional fixes after several years.
https://gitlab.com/lilypond/lilypond/-/issues/3807
https://gitlab.com/lilypond/lilypond/-/issues/4062
https://gitlab.com/lilypond/lilypond/-/issues/5039
Similar, but just multiple patches spread over subsequent releases.
I think it would be sufficient to have the final release that included
all commits, but wanted to check back if everybody agrees on that.
